Which set of coordinates, paired with (-3, -2) and (-5, -2), result in a square?

dsp73

Answer:

Step-by-step explanation:

The given coordinates are -3 -(-5) = 2 units apart on the horizontal line y=-2.

Then the needed coordinates will be on the vertical lines x=-5 and x=-3, and will have y-coordinates that are different from -2 by 2: either -4 or 0.

The points that meet these requirements are (-3, 0) and (-5, 0).

The ratio of the perimeters of two similar triangles is 4:7. What is the area of each of these triangles if the sum of their are

Mashcka [7]

Answer:

The area of triangles are 16 cm^2 and 49 cm^2

Step-by-step explanation:

we know that

If two figures are similar, the ratio of its perimeters is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the smaller triangle in square centimeters

y ----> the area of the larger triangle in square centimeters

we know that

$z=\frac{4}{7}$

$\frac{x}{y}=z^2$

$\frac{x}{y}=(\frac{4}{7})^2$

$\frac{x}{y}=\frac{16}{49}$

$x=\frac{16}{49}y$ -----> equation A

$x+y=65$ ----> equation B

solve the system by substitution

substitute equation A in equation B

$\frac{16}{49}y+y=65$

solve for y

$\frac{65}{49}y=65$

$y=49\ cm^2$

Find the value of x

$x=\frac{16}{49}(49)$

$x=16\ cm^2$

therefore

The area of triangles are 16 cm^2 and 49 cm^2

Can someone help me find the maximum or minimum value?

Elden [556K]

Answer:

(c) Minimum value is -16.

Step-by-step explanation:

This will have a minimum value because the leading coefficient is positive.

We can find the minimum value by converting the function to vertex form:

f(x) = x^2 + 4x - 12

f(x) = (x + 2)^2 - 4 - 12

f(x) = (x + 2)^2 - 16.

The minimum value is -16.

So when you draw the graph the turning point is at (-2, -16).
